HEAD-HOLDERv FORl CAN-HEADING MACHINES.

SPECIFICATION forming` part of Letters Patent No. 416,537, dated December 3,y 1889.

Application filed May 20. 1889. Serial No. 311,364. (No model.) l

To all whom, it may concern:

BeE it known that I, EDWIN E. ANGELL, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain newl and useful Improvements in Head-Holders for Can-Heading Machines, of which the following is a specification.

This invention relates to machines for applying flanged heads to cylindrical can-bod- 1es, and particularly to themechanism shown in my pending application for Letters Patent filed February 18, 1889, Serial No. 300,247, said mechanism including a holder or carrier to receive a flanged can-head, jaws pivotally connected to said holder to hold a can-head therein, mechanism for closing and opening said jaws to cause them to alternately hold and release the can-head, and mechanism for reciprocating said holder and giving it a tipping movement, whereby the\holder is first moved toward a suitably-held can-body and caused to apply the head thereto, and is then removed from the can-body, leaving the head thereon, the jaws, which were closed on the can-head during the forward movement of the holder, being opened after the application of the can-head, so that on the ,returning movement of the holder they pass over the applied head without contact with it.

The present invention consists in certain improvements in the means for opening and closing the head-holding jaws, which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of the head-applying mechanism above referred to provided with my improvements. Fig. 2 represents atop view of the same. Figs. 3 and 4 represent, respectively, a side and top view of the head holder orcarrier and portions of the supporting and operating devices. Fig. 5 represents a section on line 5 5, Fig. 3.

The same letters of reference indicate the same parts in all of the figures.

In the drawings, j represents the head ,holder or carrier, in the forward end of which is a cavity p, formed to receive a flanged canhcad. IIn said cavity is a plunger q, attached to a rod r, which is adapted to slide longitudinally in said holder and in a guide s',

which is formed on a swinging. frame s, said frame being pivoted at 3 to an arm 2, affixed to a slide w, which is fitted tc move between guides y y on the supporting-frame. The holder j is fitted in a socket in the frame s, and said frame, with the slide w, is moved longitudinally to carry the holder j and the head-holding jaws thereon toward and from a can-body to be headed, said body being held for the heading operation by suitable clamps or holders, as shown in my application for patent for can-heading machines filed February 18, 1889.

The devices thus far described, as well as other parts not here specifically referred to, are the same in their construction and operation as the parts similarly lettered in the drawings of my former application, Serial No. 300,247.

m m represent the head-holding jaws, which are formed on the forward ends of levers m fm, said levers being pivotally connected by bolts 7a k to ears on the holder, as in the application last referred to. .f

A A represent springs, which are placed in sockets in the holder j, and bear against the forward ends of the levers m m, pressing said ends and the jaws m m thereon outwardly, so that said jaws stand normally in their opened position or separated so that they will pass over a can-head without contact therewith.

The rear ends of the levers m m are curved inwardly and bear against the conical or tapering forward end of a collar B, which is fitted to slide on the reduced rear portion of the holderj. Said collar is provided with a peripheral groove C, which receives studs D D on the forked ends of the lever E, which lever is pivoted at F to a fixed ear G, attached to the supporting-frame, and has at its lower end a trundle-roll entering a camgroove H in a roll I, affixed to the shaft f, which actuates the other parts. The rotation of said shaft causes the cam-groove h to oscilla-te the lever E, said lever moving the collar B back and forth. When the collar is moved forward or toward the outer end of the holder j, its tapered end is inserted between the rear ends of the levers m 'm and forces said ends outwardly, forcing inwardly the opposite ends of said levers and the jaws fm', and caus- IOO ingsaid jaws to hold a can-head in the cavity havinr the hefnl'reeeivingl cavity, the levers p. Then the collar is moved backward, it is withdrawn from between the levers m. ym, and the springs A A are allowed to throw the jaws m m outwardly to their normal positions.

The described movements of the collar ll are timed so that the jaws are forced inward or closed prior to the insertion of a can-head in the cavity p, remain closed duringl the forward movement of the holder, are opened just before the baelnvard movement of the holder, and are held open until the jaws pass over the applied head.

I claiml. The combination of the can-head holder having the headreeeiving cavity in one end, the levers pivoted to the head at opposite sides thereof, the jaws on the outer ends of said levers arnang'ed to project partly over the said cavity, springs whereby the jawsare normally pressed outwardly, and mechanism for forcingr outwardly the inner ends of said levers and thereby closing` the jaws, as set forth.

2. The combination of the can-head holder m `m, pivoted to opposite sides of the head, the jaws on the outer ends of said levers, the springs whereby said jaws are normally opened, the tapered collar interposed between the inner ends oi said levers, and means for reciprocating' said collar, as set f'orth.

il. The combination of the can-head holder, the levers m m, pivoted thereto, the jaws on said levers, the springs whereby said jaws are normally opened, the tapered collar arranged to act on said levers and thereby close the jaws, the forked lever pivoted centrally to a iixed support and engaged at one end with said collar, and a positirely-rotated can; engaged with the other end of said lever, as set forth.

In testimony whereotl have signed myname to this speeiiieation, in the presence oi two subscribingl witnesses, this 13th day of May,

EDWIN E. ANGELL. Witnesses:
